- #3Will the diffraction effects from a slit be more or less clearly visible if the slit-width is increased?Ans : The width of the central band is inversely proportional to the slit width. So, as the width of the slit is increased, the central band will become less wider and further bands will start merging in them. Hence, diffraction effects will be visible less clearly.
